The drawings illustrate a convenient Way to manufacture rakes in accordance with the invention in which the pieces 'l indicate the tines or prongs and 2 indicates the head to which the tines are fastened. In this case the contact 3 is merely a block of conducting material against which the head 2 is seated and the Contact i is formed as a clamp to grip the inclined sides of the'tine as shown.

The head 2 is shown as a strip of metal triangular in cross-section, but might obviously be of any other suitable form whereby an inclined surface would be presented to the end of the tine, inclined to the line of pressure transmitted to the work through the contacts 3, 4, to upset the same and effect the Welding 'of the two'pieces.

It will be observed that a rake constructed as shown and described will be capable O standing great strain owing to the increased bearing surface of the tines on the head v and the large Welded union between the two "parts effected thereby.

5 indicates the prong to which the handle 'comprising solid metal tines united to an' edge orf a solid metal head having inclined sides, the \`nes beingsplit and having'A a bearing ontne inclined sides .of the head.

2. A rake consisting of a triangularshaped Asolid metal head and solid metal tines welded to the head, the tines be split and having a bearing-on the sides o fthe triangular head and a shank for the handle Welded Ato the head.
